MAP2K for JNK pathway. MEK4 is weakly activated by TNF and IL-1.
a_re1315( Apoptosis ):
in mouse embryonic cells, with targeted disruption of either MAP2K4 or MAP2K7, the phosphorylation pattern of JNK reveals sequential phosphorylation by these MAP2Ks

MLK3 and MLK2 two MAP3Ks of JNK pathway can interact with RAC1 in a GTP-dependent manner.
MEKK2 and MEKK3 can activate JNK P38 and ERK pathways.
TAO kinases are novel MAP3Ks that specifically regulate P38s.
ASK1 is a MAP3K and can activate both JNK and P38 pathways.
MEKK1 selectively activates the endogenous JNK pathway. MEKK1 can activate MEK4 and MEK7 in vivo.
MEKK4 is a MAP3K and can activate both JNK and P38 pathways.
TAK1 is a MAP3K. It is able to activate both JNK and P38 pathways.
Endogenous TAK1 is activated by TGF-beta IL-1 and TNF. TAK1 can phosphorylate and activate MEK4 MEK3 and MEK6.
MLK3 has the potential to positively regulate the ERK / MAPK pathway by directly phosphorylating and activating MEK.
Expression of GADD45 genes in mammalian cells strongly activates co-expressed MTK1 as well as P38 and JNK the MAPKs downstream of MTK1. TAO kinases are MAP3Ks that function upstream of P38 and JNK.

s_mpk1_re156( Survival ):
